Administrator Guide

Solution Check the binding in vSphere by opening the iSCSI Initiator Properties window. If
no VMkernels are shown, click Add, select the VMkernel that corresponds to your
iSCSI (uncached) network, and click OK. Click Close on the Properties window and
when prompted to rescan the adapter, click Yes.
Cannot Connect to Cluster Nodes
Possible Cause Time synch issues are preventing Enterprise Manager from connecting to the
cluster nodes. The cluster appears to be configured correctly, but in the Overview
page, no Fluid Cache connections are active.
Solution Make sure that you have enabled Network Time Protocol and that in the vTools
control panel, Synchronize guest time with host is not selected. (For more
information, refer to the VMware document Timekeeping in VMware Virtual
Machines).
Fluid Cache License Is Expired
Possible Cause System settings such as changes to the system date cause the current Fluid Cache
license to expire. You can still access data on cached volumes, but performance is
degraded because the Fluid Cache cluster has been placed in maintenance mode
and caching is no longer active.
Solution Check the status of the license file by selecting the Fluid Cache cluster in
Enterprise Manager and referring to the status shown on the Events or Cache tabs.
If the license is expired, make sure that your system settings for date and time are
correct. If it is not correct, set the appropriate date and time. Take the Fluid Cache
cluster out of maintenance mode by selecting the cluster in Enterprise Manager,
clicking Edit Settings in the Summary tab, and then clearing the Maintenance
Mode option.
Possible Cause Fluid Cache for SAN is running on an evaluation license (typically 90 days) and that
time period has been exceeded. You can still access data on cached volumes, but
performance is degraded because the Fluid Cache cluster has been placed in
maintenance mode and caching is no longer active.
Solution Check the status of the license file by selecting the Fluid Cache cluster in
Enterprise Manager and referring to the license type shown on the Events or Cache
tabs. If the number of days remaining is zero, contact your Dell representative to
purchase a Fluid Cache for SAN license. After activating the new license, take the
Fluid Cache cluster out of maintenance mode by selecting the cluster in Enterprise
Manager, clicking Edit Settings in the Summary tab, and deselecting Maintenance
Mode.
Fluid Cache License Is Invalid
Possible Cause The license file is invalid if it is in any way modified. This causes unsuccessful digital
signature validation.
